Science Daily announced today that researchers at UT Dallas have developed an imager chip for potential use in cell phones and other portable electronic devices that would enable them to see through opaque materials including walls, wood, plastics, paper and other objects.
The new imaging technology capitalizes on research in the terahertz range of the electromagnetic spectrum, which is close in frequency to the millimeter wave technology in use by the TSA in their new body imaging scanners in many airports.
Law enforcement agencies are actively pursuing such technology for their own use, including the New York Police Department, which is already testing such devices, developed in conjunction with the Pentagon, to check for concealed weapons.
Advocates tout such scanning technology as an improvement over stop-and-frisk, but several privacy groups have raised concerns, citing Fourth Amendment protections.
The potential application of terahertz scanning in consumer electronics raises its own serious privacy concerns. Imagine a world in which an opaque walls are easily seen through by cell phones. Coming soon?
